acer 3d projector 4 mths old used 3 times ?

Bought this just a few months ago in February 2012 from Argos for 250.00. Absolutely cracking picture, ideal for streaming movies and watching DVD’s on the big screen as well as powerpoint presentations etc. So the technical stuff (which doesn’t mean that much to me): The Acer X110P projector boasts outstanding performance with rich colours, superb clarity, excellent 3D entertainment and a true 24p frame rate for a cinema-like experience. A long-lasting lamp life and practical lamp design keep maintenance costs low. And, Acer EcoProjection technology reduces power in standby mode from 5 W to 1 W, while Acer ColorSafe technology preserves the colour integrity of your images even after prolonged use of the projector. Enjoy immersive visuals for games, movies and photographs beamed from the Acer X1 series projector, certified for leading 3D solutions. Beyond that, advanced technologies depict optimal colour balance and allow accurate image projection, even on coloured walls. Plus, an exceptional resolution and high brightness project crystal-clear images. • Projector Type - DLP • Max Resolution - SVGA (800x600) • Brightness - 2700 ANSI lumens • Contrast Ratio - 4000:1 Link to Argos page: http://www.argos.co.uk/static/Product/partNumber/9384394.htm
